[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example: Reference Figure 1-7 The forging die for a cylinder joint shown in the figure comprises an upper die base 1, a lower die base 2 and a stopper 3. The stopper 3 is arranged on the periphery of the stamping groove of the lower die base 2. The stamping groove of the upper die base 1 is matched with the inner wall of the annular stopper 3. Therefore, when performing forging operations, compared with the existing lower die base structure, this embodiment reduces the burrs generated during each processing of the forging parts, thereby improving the utilization rate of raw materials.

[0026] The above-mentioned blocking member 3 is composed of a left member 5 and a right member 4. After the forging operation is completed, the connection limit between the two is released by toggling the connecting mechanism. The left member 5 and the right member 4 are respectively moved in the guide groove 21 through the guide blocks provided on their bottom surfaces to expose the forged parts, thereby facilitating the staff to take them away and proceed to the next step of the operation.

[0027] The handle 6 provided on the outer wall of the blocking member 3 is designed to facilitate the staff to carry it, thereby improving its portability.

[0028] The connecting member 7 and the limit block 8 of the connecting mechanism are respectively arranged in the left groove 51 of the left member 5 and the right groove 41 of the right member 4. The left groove 51 and the right groove 41 correspond in position and in size. The connecting member 7 is hinged in the left groove 51, and its free end has a hemispherical cross-section. The limit block 8 is wedge-shaped. Therefore, when the two are in use, the free end of the connecting member 7 cooperates with the inclined surface of the limit block 8 to achieve the purpose of autonomous connection and save docking time.

[0029] The top surface of the connecting member 7 is provided with a hook groove 71 , in which a cross bar is provided for releasing the function of the connecting member 7 and the limiting block 8 .

[0030] The practical working principle of the present invention is as follows: the raw material is placed in the punching groove of the lower die seat 2, and then the upper die seat 1 is started to descend, the punching groove of the upper die seat 1 corresponds to the position of the stopper 3 on the lower die seat 2, and the size matches, so as to reduce the burrs generated during the processing of the raw material. After the forging operation is completed, the upper die seat 1 moves up, and then the staff uses a stick-shaped tool to penetrate into the hook groove 71 of the connecting member 7 to release the connection between the connecting member 7 and the limit block 8, so that the right member 4 and the left member 5 become separated, and then the stick-shaped tool is inserted into the handle 6 and moved outward, so that the left member 5 and the right member 4 slide in the guide groove 21 respectively through the guide blocks provided on the bottom surface, completing the splitting of the stopper 3, exposing the forged member, and then taking away the forged member.

[0031] When processing is required again, the right part 4 is pushed back to the middle, and then the left part 5 is also pushed back to the middle. The connecting part 7 on the left part 5 climbs upward through the cooperation of the hemispherical shape at the end and the inclined surface of the limit block 8, and then sinks under the action of gravity, completing the assembly of the left part 5 and the right part 4, and then repeating the above operation.

[0032] The electromechanical connection involved in the present utility model is a common means used by those skilled in the art, and technical inspiration can be obtained through a limited number of tests, which belongs to common knowledge.

[0033] Components not described in detail herein are prior art.
